Allowing the user to change the size and offsets of
the PostScript window would pretty much negate the
entire purpose of cgWindow and (by extension) cgControl,
which it to provide a *resizeable* graphics window
that can be controlled by the user. PostScript output
is by design set to mimic the contents in the resizeable
window.
If you want total control of PostScript output, there
are other tools that allow this (e.g., PS_Start via
PSConfig). Programs that run in cgWindow presumably
already work in PostScript, so using these other tools
is usually as simple as calling PS_Start with the
appropriate keywords (or set the GUI keyword and do
it interactively), running the program, and calling
PS_End. Simple and efficient.
The way I would create larger margins, if that is what
I wanted, would be to use a different POSITION in my
graphics program, so that there was additional space
on the outside of my plot.
Cheers,
David
